Doss [256]

Answer: The correct option is B.

Will genetically modified crops increase profit for farmers?

Explanation:

This is because genetically modified crops are produced to achieve a particular advantage. Genetically modified crops are produced with some traits that are beneficial to Agriculture. Farmers choose genetically modified crops in order to increase yield, and produced crops that are resistant to certain diseases. These genetically modified crops are produced because of the traits that increase crop yield when farmers plant them it will increase the profit of farmers.

Hoochie [10]

Answer:

chemicals that cross the synaptic gap and bind to receptors on another neuron

found only in the central nervous system (the brain and spinal cord)

Explanation:

Neurotransmitters are defined as the chemicals that is transported from a nerve cell across the synaptic gap to the receptor of another neuron or a target cell such as a gland cell or a muscle cell.

Neurotransmitters are generated in the central nervous system (the brain and spinal cord) and are stored in synaptic vesicles.

chemicals that cross the synaptic gap and bind to receptors on another neuron

found only in the central nervous system (the brain and spinal cord)".

Scientists studying transcription in yeast (Saccharomyces cerevisiae) created an experimental strain that
Ray Of Light [21]

Answer:

Explanation:

Hello!

The scientist created an experimental strain that produces a modified RNA polymerase with a single amino acid substitution. This mutation is supposed to change the elongation rate of the mRNA during transcription.

The dependent or response variable, is the one the researchers are interested in, meaning, are the characteristics that the researcher will pay attention to and measure during the experiment.

In this example, the researcher is interested in testing the max elongation rate during transcription, which is the dependent variable of this experiment.

In the second part of the experiment, both strains of yeast, wilds, and experimental, where exposed to 40ug/mL solution of amanitin and recorded the maximum elongation rate of the RNA. This is naturally to test the effects of amanitin over the elongation rate of the mRNA in both strains.

The control group is a set of experimental units that are exposed to the same conditions as the experimental groups, with the exception that they receive no treatment (or they receive a "no effective" treatment often called a placebo). The purpose of a control group is to know the natural response of the experimental units to a treatment-free environment, this way when comparing both groups, the researcher will be able to observe the differences or changes due to the applied treatments.

In the second experiment, there are missing two control groups, one made of the wild strain and the other made of the experimental strain, exposed to the same conditions as the treated strains.

I hope this helps!
